Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable hampers for laundry are either not durable enough to handle heavy loads or occupy too much space when assembled, making them impractical for long-distance transport and storage.
Innovation Solution
A knock-down hamper design featuring a base frame with caster assemblies, a supporting frame assembly with U-shaped frames, and a fabric body with corner sleeve pockets, allowing for quick assembly and minimal storage space, while providing stability and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If collapsible hampers are used, then ease of assembly and storage is improved, but durability and load-bearing capacity deteriorate
Solution Approach 1:
The hamper is divided into separate components (base frame, supporting frame assembly, fabric body) that can be easily assembled and disassembled, yet when assembled form a structurally sound unit capable of bearing heavy loads. The segmentation allows for compact storage while maintaining durability during use.
2Reliability
If larger hampers with rollers are used, then load-bearing capacity and transport capability are improved, but storage space requirement deteriorates
Solution Approach 1:
By segmenting the hamper into separate components that can be collapsed and nested, the storage volume is dramatically reduced while the assembled structure maintains the load-bearing capacity and roller functionality needed for transporting heavy laundry loads.
3Volume of stationary object
If collapsible hampers are used, then storage space is improved, but transport capability deteriorates
Solution Approach 1:
The collapsible design segments the hamper into compact components for easy storage, while the assembled structure incorporates rollers and a sturdy frame that enable effortless transport of heavy laundry loads, thus achieving both compact storage and excellent transport capability.

AI summary
A hamper has a base having a base frame with a base shelf provided inside the base frame, and a plurality of caster assemblies secured to the base frame. A supporting frame assembly has two U-shaped frames, with each U-shaped frame having a horizontal base bar and two vertical bars extending from opposite ends of the base bar, with the two U-shaped frames coupled to each other at the center of each base bar, and with the base bars secured to the base. A fabric body has a plurality of side walls, and four vertical corner sleeve pockets, with each vertical corner sleeve pocket defining a channel that receives a separate vertical bar. A top frame secured to the upper ends of the vertical bars.
